Abstract
Metal injection molding process has been applied for Ti-6Al-4V alloy and the effects of process conditions have been studied on microstructure formation and mechanical properties of the compacts. Sintering at 1223K results in relative density higher than 96%. Oxygen content increases with sintering time, which gives an undesirable effect on elongation of the sample. Tensile strength about 950 MPa has been obtained, which is at the same level with that of cast alloy. The equi-axis a structure increases with time of sintering. The coarse a structure has been shown to give local sites for crack initiation.
